Tenshin Nasukawa
The former five weight world champion was initially expected to come out of retirement this year but looks like he'll stick to exhibitions.
Mayweather's last action in the ring was his exhibition fight against Japanese kickboxer Tenshin Nasukawa on New Year's Eve.
The undefeated Floyd Mayweather said that there are "no talks about me and Manny Pacquiao fighting [in] a rematch."
